Electrohydraulic Actuator

PVED-CX

The extensive PVG 32 product line now includes a
PVED-CX digital actuator to ensure entrance into the
SIL 2 and CANopen world.

The PVED-CX helps OEM to reach a high performance
level while facilitating compliance with the safety
demands of Machinery Directive 2006/42/EC.

Target applications are cranes, man lifts, telehandlers
and special purpose vehicles.

The CANopen protocol is designed for proportional
valve controls and can be used in any application.

All our know-how is channeled into the electronic, software, and
mechanics of the PVED-CX. The PVED-CX is designed for optimum
reliability and safety – the result of an innovative and very
thorough development process.

The PVED-CX is SIL 2 certified according to IEC 61508 by TÜV Süd.

Control and safety principles for PVED-CX

The safety approach of the PVED-CX is based on self- and
neighbor-monitoring combined with the ability to shut down all
neighbor modules. Spool movement, internal electronics, and
software processes are redundantly monitored.

Our complete valve safety concept includes PVG with PVSK.

When using PVED-CX in combination with PVG with PVSK, oil flow
is controlled locally by the PVSK. Oil flow to the application can be
shut down by both PVSK and valve without influencing other
functionality on the vehicle.

PVED-CX – supporting OEMs to meet the required Performance
Level.
